ucal applic cirochemistry • gain experience entering data and calculations into an electronic document or notebook This experiment relies upon the Electrochemical Cells simulator written by Dr. Gary L. Bertrand at the University of Missouri-Rolla and available at: http://web.mst.edu/~gbert/Electro/Electrochem.html Follow the below instructions, record all your responses in your document, export the final version as a pdf, and upload the pdf file to your course CANVAS page by the due date.
2 3 5 Part 3. Concentration Cells 3 A. Voltage Measurements. Set "Level" to 0. Set the same metal (of your choosing) and solution for both the right and left electrodes to provide matching solutions. Set both Concentrations to 1 M, measure the Cell Voltage, and record your result below. Change the Concentration on the Left to 0.1 M, measure the Cell Voltage, and record your result below. Repeat for 0.01 M, 0.001 M, and 0.0001 M on the Left. Left Concentration (M) Right Concentration (M) Cell Voltage (V) 1 1 # * 0.1 1 0.01 1 0.001 0.0001 1 3 B. Linear Fit. Use Excel or Google Sheets to make a plot of y=Cell Voltage # # #
3 4 3 D. Linear Fil use Excer or Google sheets to make a piot OT y=Cell Voltage Versus x = log (Q) = log( Left Concentration / Right Concentration) Fit your data with a Trendline, and display the equation. Paste a screenshot of the plot below. Hint: For help on Trendline on a Google Sheet, see https://www.mrwaynesclass.com/labs/read ... oogle.html insert screenshot here> 3 C. Comparison to Nernst Equation. Recognizing that the Nernst Equation (0.0592 V /n) * log Q E=Ecell Has the form of a straight line y=b+m*x we see that the theoretical value of slope of a plot of y = E versus x = log Qis I m=-0.0592 V /n Compare the value of the slope from the Nemst equation to the slope from your concentration cell. (Hint: They should be close.) slope (Nernst equation) = -0.0592 V / # =# slope(concentration cell) = #
